When most people think of Casino, they envision one of the megaresorts in Las Vegas, a dazzling, noisy place with neon lights and games. But casinos can also be found in many other places, from small card rooms to racinos at racetracks. And even some bars and grocery stores have casino-type machines.

While musical shows, lighted fountains and shopping centers help lure gamblers in, the vast majority of a casino’s profits come from games of chance. Slot machines, black jack, roulette, craps and keno bring in billions of dollars in profits each year for the owners of these establishments.

Casinos are highly profitable, but they’re not without risk. Some people become addicted to gambling, and studies suggest that compulsive gamblers generate a large percentage of the industry’s losses. Casinos are also often criticized for shifting money from other local businesses and reducing economic activity.

To offset these risks, casinos spend a great deal of time, effort and money on security. Casinos are monitored by surveillance systems that capture all the activity on the gambling floor and in the betting booths. The information is stored in a secure database and can be viewed by casino managers.

In addition to the cameras, casino security staff monitors players’ behavior to prevent cheating and stealing. If a player is suspected of violating rules, the security team can alert floor supervisors or pit bosses. And the security team keeps a close eye on table games, checking for signs of collusion between players or any other suspicious behavior.
